DANIEL c. nrcxsom'or NEW YORK, n. Y., ASSIGNOR 4T0 announcer. nnsnnncn rnonoc'rs nvc., or NEW YORK, n. x, a conroaa'rron or DELAWARE norm surroa'r Application filed December 19, 1929. Serial No. 415,257.

This invention relates to horn supports and more particularly to horn towers for use in sound picture installations.

The primary object of the invention is to provide an efficient support of simple construction for adjustably positioning a horn.

In accordance with one embodiment, the invention contemplates the provision of a movable tower having three movable platforms supported one on top of the other, the lower two platforms providing straight-line movement transversely of each other and the uppermost platform being rotatable, The horn which is connected to sound picture equipment is adjustably suspended from the uppermost platform on the tower' whereby the position of the horn may be adjusted to obtain the best acoustical effect.

Other objects and advantages of the invention will become apparent from the following detailed description when considered in con unction with the accompanying drawings, wherein Fig. 1 is a fragmentary front elevational view of a horn tower support embodying the invention;

Fig. 2 is an enlarged fragmentary plan view thereof;

Fig-3 is an enlarged fragmentary side elevational view of the horn support on the tower;

Fig. 4 is a plan view of a modified horn support in which only two movable platformsare used in the tower, and

Fig. 5 is a partial side elevational view of V the modified horn support, shown in Fig. 4.

Referring now to the drawingswherein like reference numerals designate the same parts throughout the several views, four uprights or standards 1O and a plurality of cross pieces 1111 are assembled to form the frame of a rectangular tower 12, which is mounted on casters 1313 to permit it to be moved readily to different locations. As shown in Figs. 1 to 3, inclusive,the upper front and rear 'cross pieces 11 are of'L-shaped cross section to form guide members which provide a runway for rollers 1515 supporting a platform 16 (hereinafter called the lower platform) which hasL-shaped guide members 17-17 secured thereon for guiding and supporting rollers 1818 of an intermediate or middle platform 19. This latter platform carries on its u' per surface a top platform or frame 20 whlch is rotatably supported by three rollers 21, 22, and 23 for expediting the movement thereof.

The frame or platform 20 includes two arms -31, from which thefront end of a sound picture horn 32 is suspended by chains or ropes 3333 and an arm 34 is positioned at right angles to the arms 30-31 and carries a swivel pulley 35 (Fig. 3) over which a chain or rope 36 is passed for adjustably supporting the rear end of the horn in;a manner analogous to that clearly shown ,"in Fig. 5. Slidably positioned in a slot 37 of the arm 34 are two locking members 3839, each having a depending hook portion 40 projecting through a'rectangular opening of the middle platform 19 and adapted to engage. and

clamp the inner edges thereof when nuts 46' 46 threaded on the upper ends of the memin a plate 25 (Figs. 2 and 3) fastened to the arm 34 so that the top platform 20 is rotatable about the stud- The locking members 3839 prevent the top platform 20 from being moved off of the middle platform. Likewise, the middle platform is equipped with two locking .members 4949 which engage the underside of the lower platform to retain the middle platform 19 in a predetermined position with respect to the lower platform 16. The lower platform is also provided with locking members 58-58 (Fig. 3) which arev adapted to grip the underside of the upper cross pieces 11 of the tower and the upper ends of these members serve as stops to prevent the middle platform 19 from being run ofl the ends of its guide members 17-17.

In the use of the above described equipment in sound picture productions, the horn tower is moved about the'stage to a desired location adjacent the picture screen. Thedefinite location of the horn within the tower relative to the screen is then adjusted by manually moving the three platforms 17, 19, and 20 in the tower to desired 'ositions and locking them in place and the liorn is tilted by means of the pulley 85 and the rope 36 to thereby properly position the horn to obtain the best acoustical effect in the theater.

' In another embodiment of the invention disclosed in Figures 4 and 5, the tower 12 has secured on its top two L-shaped guide members 50-50 supported by a frame member 11 and a cross piece 51. A platform 52 is movably supported on the guide members 5050 by rollers or casters 53-53 whereby.

the platform can be expeditiously moved longitudinally of the tower. Bolts 5454 se- 1 cured to laterally extending portions 55'-55 I of the guide members 50-50 protrude up- 'wardly through slots 56-56 in the platform 52 and have nuts 57-57 threaded thereon for clamping the platform in a predetermined position on the tower. Supported by three.

rollers 6060 on top of the platform 52 is a triangular frame 61, from the base end of which a sound picture horn 62 is suspended by ropes or chains 63-63. The apex of the triangular frame has pivoted on its underside a pulley 64' over which passes a rope or chain 65 having one end fastened to the rear portion of the horn 62 and the other end secured to a tie-bar- 69 forming a part of the tower. By means of the rope and the pulley the horn can be tilted at any desired angle. Secured to and forming a part of the triangular frame 61 is a plate 70 which is pivoted on an upright bolt 71 secured to the latslots 7 37 3 in the platform 52 and are provided with nuts 7474 threaded thereon for locking the frame 61 on the platform.

It is believed to be obvious, without further description, that the frame 61 and the horn suspended therefrom can be rotated about the bolt 71, also that they can be moved transversely of the tower by means of the platform 52, and that by means of the rope 65 and pulley 64 the horn can be tilted relative to the tower to obtain the desired acoustical effect in any sound picture installation.
